Detailed explanation-1: -The vital capacity (VC) measures the maximum amount of air that can be inhaled or exhaled during a respiratory cycle.
Detailed explanation-2: -Total Lung Capacity(TLC) It is the maximum volume of air the lungs can accommodate or sum of all volume compartments or volume of air in lungs after maximum inspiration. The normal value is about 6, 000mL(4‐6 L).
Detailed explanation-3: -Tidal volume (TV) is the amount of air that normally enters the lungs during quiet breathing, which is about 500 milliliters.
Detailed explanation-4: -Vital capacity is defined as the maximum amount of air that can be inhaled and exhaled in one breath. This term is very similar to tidal volume except tidal volume is defined as the amount of air inhaled and exhaled in one normal, resting breath.
